According to the issue configurating every site, with this tiny code you can configurate it.

How does it work?
1. Fill in the details of your account.
2. Load the page, you will see all configurations.
3. Open "domain.ext_config.php" which can be found under "shop/includes/config_sites/"
4. Copy everything you see in the textarea and paste it in the file you openend in step 3. (yes, you can literally paste it)
5. Modify the details, easiest way is trying to search what you want to change, and then change it in what you want.

PHP Code:
<textarea cols=100 rows=100>
<?php

$host 
'localhost';
$user '';
$pass '';
$db '';
mysql_connect($host,$user,$pass);
mysql_select_db($db);

$query mysql_query("SELECT configuration_key, configuration_value, configuration_title FROM configuration");
while (
$zen_conf_sel    =       mysql_fetch_assoc($query)) {
        echo 
'define(\''.$zen_conf_sel['configuration_key'].'\',\''.$zen_conf_sel['configuration_value'].'\');
'
;
        }

?>
</textarea>
Can't be done easier, right?
